| STEP | CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|
| 1 | Turn the ignition key OFF.Connect the wiring harness connector from the accelerator pedal potentiometerTurn the ignition key ON.Select the following system on the diagnostic equipment: Diesel electronic injection control unit EDC16C39 CF4/EOBD CAN (EP engine 1.9).Check that error P0641 – Power supply to sensors 1 is “Present”.Move on to Step 5 | Move on to Step 2 |
| 2 | Turn the ignition key OFF.Disconnect the wiring harness connector from engine control unit connector ATurn the ignition key ON.Check that the resistance across pin 9 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 3 | Check that the resistance across pin 30 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 4 | Replace the accelerator pedal Op. 1068A20 ACCELERATOR PEDAL WITH BUILT-IN POTENTIOMETER - R.R and check the fault has disappeared.The test can be considered over | Repair the original accelerator pedal and replace the engine management control unit. Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R |
| 5 | Turn the ignition key OFF.Disconnect the wiring harness connector from the timing sensor.Turn the ignition key ON.Select the following system on the diagnostic equipment: Diesel electronic injection control unit EDC16C39 CF4/EOBD CAN (EP engine 1.9).Check that error P0641 – Power supply to sensors 1 is “Present”. | Replace the timing sensor Op. 1060G22 CAM ANGLE SENSOR - R.R |
| 6 | Turn the ignition key OFF.Disconnect the wiring harness connector from engine control unit connector ATurn the ignition key ON.Check that the resistance across pin 45 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V.Move on to Step 8 | Move on to Step 7 |
| 7 | If faults are present, repair or if necessary replace the electrical wiring between the engine control unit and the accelerator pedal potentiometer. See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT Replace the wiring if necessaryThe test can be considered over | Replace the accelerator pedal Op. 1068A20 ACCELERATOR PEDAL WITH BUILT-IN POTENTIOMETER - R.R |
| 8 | Turn the ignition key OFF.Check that the resistance between pin 30 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is more than 500 kOhm. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 9 | Disconnect the wiring harness connector from engine control unit connector BTurn the ignition key ON.Check that the resistance across pin 11 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the timing sensor and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 10 | Turn the ignition key OFF.Check that the resistance between pin 11 (wiring side) of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is more than 500 kOhm. | Repair or if necessary replace the electrical wiring between the timing sensor and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 11 | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R | |
